Motivation and Background¶

Give an overview of the project, motivation, background and goals.

Eve Online is a Massively Multiplayer Online Role-Playing Game, or MMORPG for short, set in space. To go out of the space stations and explore in Eve, you need to use space ships. Each of the different ships has different attributes. One of these attributes is slots. In these slots you can fit modules which increase the capabilities of your ship. Some types of modules are:

  • Weapons: Used to deal damage to the enemy
  • Electronic warfare: used to debuff other ships
  • Logistics: used to buff other ships
  • Tanking: gives your ship more health/regeneration

Of course, there are many more categories, and each category has many different modules.

There is obviously some strategy as to which modules you would put on your ship. It is well known, for example, that you should not bring a pickaxe to a gunfight.

By using ship data from Eve, I would be able to not only gain insight into the different strategies for fitting modules on ships, I would also be able to know how the general community acts in this way. Potentially, this could have a link to wider human psychology.

There is one main goal: To find out the most common situations where given modules are used.

Summary of Research Questions & Results

Repeat your research questions in a numbered list. After each research question, clearly state the answer/conclusion you determined. Do not give details or justifications yet — just the answer

As the number of modules is very large, the analysis will group modules based on what they do.

  1. In a given region, are the modules more rarely used based on the availability of the modules in the region?

No correlation, however there are some modules rarely used.

  1. Given the price of a ship, are modules of a similar price more commonly used than on average?

Kind of, but many outliers

  1. Is the popularity of modules different when fighting player and non-player enemies?

Yes.

  1. Given a certain module, which modules (and how many) are most commonly fit alongside it?

Mostly modules that synergize, but other pairs exist.

Dataset

Numbered list of dataset (with downloadable links) and a brief but clear description of each dataset used. Draw reference to the numbering when describing methodology (data cleaning and analysis).
  1. https://data.everef.net/killmails

This data contains descriptions of about 70% of all the kills that have happened in Eve. These descriptions are called "killmails". Killmails are a snapshot of the ship, its pilot, and its surroundings at a point in time - the point in time that the victim ship was destroyed. As players exploring in ships have a not low chance of getting killed, killmails cover most of the different situations in Eve. Killmails provide not only the ship and the modules on it at the time it was killed, but also the attackers that killed the ship, where the ship was at, and the pilot's alliance at the time.

  1. https://www.fuzzwork.co.uk/dump/latest/

This contains a lot of information about ids and attributes of things in the game. Some of the info that will be used is below.

  1. https://www.fuzzwork.co.uk/dump/latest/invTypes.csv

This maps the item's id to its name and details.

  1. https://www.fuzzwork.co.uk/dump/latest/invFlags.csv

This maps a flag to slots in the ship, useful to find out which items were fit on the ship and which items were carried in cargo.

  1. https://www.fuzzwork.co.uk/dump/latest/mapSolarSystems.csv

This maps the solar system's id to the name of the solar system, its security status, and other attributes.

  1. https://www.fuzzwork.co.uk/dump/latest/mapRegions.csv

This maps the region ID to the name of the region, and in certain cases, the faction the region belongs to.

  1. https://www.fuzzwork.co.uk/dump/latest/chrFactions.csv

This maps the faction ID to the name of the faction, its race, home solar system and corporation ID.

  1. https://esi.evetech.net/latest/markets/regionid/history?type_id=itemid

This is the historical market data from 1/8/2021 onwards. Replace "regionid" with the region id and "itemid" with the item id to get results.

Methodology¶

You should demonstrate the data science life cycle here (from data acquisition to cleaning to EDA and analysis etc).

Data Acquisition¶

Display the data which will be used in the project. The data should be saved in .xlsx or .csv format to be submitted with the project. If webscraping has been done to obtain your data, save your webscraping code in another jupyter notebook as appendix to be submitted separately from the report. Import and display each dataset in a dataframe. For each dataset, give a brief overview of the data it contains, and explain the meaning of columns that are relevant to the project.

Data Cleaning

For data cleaning, be clear in which dataset (or variables) are used, what has been done for missing data, how was merging performed, explanation of data transformation (if any). If data is calculated or summarized from the raw dataset, explain the rationale and steps clearly.

Part 1: The killmails¶

Dataset used: https://data.everef.net/killmails

When the killmails are downloaded, they are in text files with json objects scattered in them. They are extracted and placed into dataframes. The columns are standardized for easy formatting. They are then saved and removed from memory when they are too large to fit (~5GB)

The csv files are combined into one and then a systematic sample (1 row every ~150 rows) is taken out. This is where sample comes from.

Part 2: The market data¶

The market data comes from the website in json format. Each entry is stored as a row, with the dates having no data being turned into NaN. The average is taken out along with the date, and the index of the row is the item id.

Part 3: The market data part 2¶

This time the volume is taken instead of the average, and the mean of all the days is taken to filter out NaN data.

Part 4: The pricing¶

A function is made to take the json of items out of the column. The items are then filtered out based on the 'flag' and then the prices are extracted from the market data. If the price is NaN, it takes the average price. Same for the ship. The information is then stored in a dataframe.

Part 5: The pvp/non-pvp information¶

Similarly to the pricing data, the attackers and items are extracted from their jsons. Based on how the attackers are, the items are saved into a dataframe.

For more information on the code, check the appendix. In the interest of time, none of the code will be placed here.

EDA

For each research questions shortlisted, outline your methodology in answering them. Discuss interesting observations or results discovered. Please note to only show EDA that's relevant to answering the question at hand. If you have done any data modeling, include in this section.

Note: data processing that takes too long will be skipped, and the finished files imported instead.¶

Q1: In a given region, are the modules more rarely used based on the availability of the modules in the region?¶

As the numbers are whole numbers, having many 0s would bias the dataset. So, we limit the data to modules with over 500 total occurences, and regions which have more than 10,000 modules recorded.

In the interest of time, calculation of the number of items found in each region throughout the killmail data has already been done and stored in region_items.csv.

In [14]:
regions = pd.read_csv("region_items.csv")
regions = regions.groupby("Region").sum()
regions = regions.T[regions.sum()>500].T[regions.sum(axis=1)>100000]

regions = regions / regions.sum()
print(regions.index.values.tolist())
for ind in regions.index.values:

Q2: Given the price of a ship, are modules of a similar price more commonly used than on average?¶

<AxesSubplot: xlabel='ship_price', ylabel='module_price'>

As we can tell, it is impossible to see anything. In addition, the few outliers make the graph too dense on the bottom left side. As the prices of ships in Eve can range from around hundreds of thousands to apparently tens of billions of currency, it may be a good idea to take the logarithm. Because we take the logarithm, we should remove all prices with a value of 0.

This way, the logarithm exists, and anyways, a module price of 0 suggests that no modules were on the ship, and we do not want to consider that as it will skew the data.

In [22]:
shipprice = shipprice[shipprice["module_price"] > 0]
sns.scatterplot(x=np.log(shipprice["ship_price"]), y=np.log(shipprice["module_price"]))
Out[22]:
<AxesSubplot: xlabel='ship_price', ylabel='module_price'>

While the logarithm removes the issue of the outliers being too far out, it is still impossible to accurately see a correlation. Many of the 1.9 million points are hidden behind other points. So, we will make the graph bigger and the points smaller, so we can see the density of the points.

In [23]:
plt.figure(figsize=(50,40))
sns.scatterplot(x=np.log(shipprice["ship_price"]), y=np.log(shipprice["module_price"]),s =1)
Out[23]:
<AxesSubplot: xlabel='ship_price', ylabel='module_price'>

With this, we can see that in the middle to right side of the graph, an increase in ship price is met with an increase in the module price. However, in the left side of the graph, the points appear to be approximately randomly scattered.

The graph has a great many outliers. We can try plotting the hue as the ship type, so maybe certain ship types deviate from the rule a bit.

Based on the pearson coefficient and the p-value, we are confident there is indeed a strong correlation between the logarithm of the price of the ship and the logarithm of the price of the modules on it. However, this means that when taking out the logarithm, the predicted values will be a few times off.

Q3: Is the popularity of modules different when fighting player and non-player enemies?¶

In the interest of time, the number of each module recorded in pvp or pve contexts has already been calculated and stored in pnp.csv.

pnp = pd.read_csv("pnp.csv").set_index("Unnamed: 0")

As in question 1, we should filter out data with very low numbers of occurences. We also take out the column PN as it is not used here.

pnp = pnp[pnp.sum(axis=1) > 100][["P","N"]]

58966 77.0 17.0

1998 rows × 2 columns

As we are only interested in comparing the relative proportions of modules used in these contexts, we will divide accordingly.

In [31]:
pnp = pnp / pnp.sum()
pnp = (pnp.T / pnp.sum(axis=1)).T
pnp = pnp.sort_values(by="P", ascending=True)
pnp

31312 0.058529 0.941471
... ... ...
21926 1.000000 0.000000
20060 1.000000 0.000000
37532 1.000000 0.000000
28351 1.000000 0.000000
20064 1.000000 0.000000

1998 rows × 2 columns

Now we plot the proportion of modules found in pvp contexts.

In [32]:
plt.figure(figsize=(200,100))
sns.barplot(x = inv["typeName"][pnp.index.values], y=pnp["P"])
Out[32]:
<AxesSubplot: xlabel='typeName', ylabel='P'>
In [33]:
plt.figure(figsize=(20,10))

sns.kdeplot(data=pnp["P"])
Out[33]:
<AxesSubplot: xlabel='P', ylabel='Density'>

From the graph, we can deduce that there are approximately equal numbers of modules used more in pvp contexts as ones used more in pve contexts. The graph is also approximately linear, so the distribution of the popularity of items is approximately uniform. However, the graph curves at the ends, so there are comparatively few modules that are almost exclusively used for fighting player or non player enemies.

Zooming on the top right side of the graph:

In [34]:
plt.figure(figsize = (20,10))
plot = sns.barplot(x = inv["typeName"][pnp[pnp["P"] == 1].index.values], y=pnp[pnp["P"] == 1]["P"])
plot.set_xticklabels(plot.get_xticklabels(), rotation=30, ha="right")
plt.show()

Zooming in on the bottom left side of the graph:

In [35]:
plt.figure(figsize = (20,10))
plot = sns.barplot(x = inv["typeName"][pnp[pnp["P"] <= 0.15].index.values], y=pnp[pnp["P"] <= 0.15]["P"])
plot.set_xticklabels(plot.get_xticklabels(), rotation=30, ha="right")
plt.show()

Upon further investigation, the items that have been found only in pvp situations are mostly structures and items on structures. This makes sense, as non-player enemies do not go around the solar system invading structures and killing them, but players do.

Q4: Given a certain module which modules are most commonly fit alongisde it?¶

In the interest of time, the number of occurences of each pair of modules (duplicates not counted) has already been calculated and stored in pairing.csv.

Now we can try to plot a heatmap to see which pairs are most commonly seen. Trust me, I have done it and with the >4000 modules it is impossible to see anything. Check "heatmap.png" to see what it looks like. It cannot be displayed here without lagging the notebook.

So instead, we will plot the item groups instead of every single item against every other item.

Once again, in the interest of time, the number of occurences of groups of modules has already been calculated and stored in region_pairing.csv.

Now we can plot the heatmap.

normalized = (regionpairs / regionpairs.sum()).T
In [46]:
plt.figure(figsize=(75,70))
sns.heatmap(np.log(np.log(normalized+1)+1), cmap='turbo')
plt.show()

The values on each row add up to 1. So in each row, the brightest points in that row are the modules that are most commonly fit alongside it. The columns are not normalized in the same way, so brighter columns are modules that appear a lot more in the dataset.

Results Findings & Conclusion

For each research question, summarize in 2-3 visualizations which will answer the question. Intrepret the results accordingly and give your observation and conclusion. The visualizations should be well presented (apply what you have learnt in Chapter 9 on data communication). The plots shown here could be an enhanced version of the EDA plots, or presented in another format.

Q1: In a given region, are the modules more rarely used based on the availability of the modules in the region?¶

In [50]:
for ind in regions.index.values:
    plt.figure(figsize=(20,8))
    bot15 = regions.loc[ind].sort_values(ascending=True)[0:]
    x = pd.to_numeric(bot15.index.values).tolist()
    plot = px.bar(x = inv.loc[x, "typeName"], y=bot15.values)
    plot.update_layout(title_text = (regi.loc[ind, "regionName"]), yaxis_title = "Relative Frequency", xaxis_title = "Module")
    plot.show()

The above graph shows the distribution of how many times each module appears in the killmails for each region. It is approximately linear in the middle, but curves towards the extremes at the left and right end. This trend appears for all the modules.

In [51]:
for ind in regions2.index.values:
    plt.figure(figsize=(15,6))
    
    bot15 = regions2.loc[ind].sort_values(ascending=True)
    x2 = bot15.index.values.tolist()
    x = pd.to_numeric(bot15.index.values).tolist()
    plot = sns.barplot(x = inv.loc[x, "typeName"], y=bot15.values, alpha=0.5, color='#FF0000')
    volums = []
    if (ind != 10000002):
        volum = volumes.loc[ind]
        for i in x2:
            try:
                volums.append(volum[i])
            except:
                volums.append(np.NaN)
        plot2 = sns.barplot(x = inv.loc[x, "typeName"], y=volums, alpha=0.5, color='#0000FF') 
        plot2.set_xticklabels([])
    plt.title(regi.loc[ind, "regionName"])
    plt.xlabel("Modules")
    plt.ylabel("Relative Frequency/Volume")
    plot.set_xticklabels([])
    plt.show()

The y axis represents the proportion of market volume for that product in the region, or the proportion of it seen in the killmail. The x axis is the item id. When we sort the module frequency in ascending order, the module volumes appear to be randomly scattered. But in general, we might see a very slight increase in the relative volume of the modules. However, it is much smaller than the increase in module frequency.

In addition, some regions appear to have the blue graph extend far above the red graph, while some regions have the blue graph almost completely contained within the red graph. This means some regions have higher average module usage, while some regions have higher average market volume. So the average usage of modules in the region does not neccessarily depend on the average market volume in that region. This also refutes the hypothesis that there is moderate correlation.

In conclusion, there is very little correlation between use of modules and their availability.

Q2: Given the price of a ship, are modules of a similar price more commonly used than on average?¶

In [52]:
plt.figure(figsize=(30,20))
sns.scatterplot(x=np.log(fshipprice["ship_price"]), y=np.log(fshipprice["module_price"]), hue=fshipprice["group"],s =1)
plt.plot([10,22], [10,22], color="red")
plt.title("Graph of module prices against the price of the ship they are on")
plt.annotate("y=x", (10, 9.8))
plt.xlabel("Natural logarithm of ship price")
plt.ylabel("Natural logarithm of module price")
Out[52]:
Text(0, 0.5, 'Natural logarithm of module price')

From the graph, the densest areas form a slight upward trend, with the exception of the purple group, which is freighters. The orange group (standard ships) forms the bulk of the left side of the graph, but the price of the modules fit on them do not increase that much as the ship increases. The blue points (precursor ships) start slightly higher than the green points (faction ships), but they both gradually trend to the same module prices

The advanced ships (red) are very rarely seen, and occupy a rather small range of values on the x axis, so any trend is hard to see.

The standard ships occupy a greater range of x values, and the price of the modules generally increases as the price of the ship increases. However the slops on the graph is very gradual, meaning the prices of modules do not increase as much as the prices of the ship they are on.

The precursor ships start slightly above the rest of the graph, meaning the prices of the modules fit on them are on average higher for the cheaper ships, but on the more expensive ships are, on average, around the same price.

Faction ships always appear to be slightly below the y=x line, meaning the modules fit on them are on average cheaper than the rest of the ship.

Freighters are an exception, with them being much more expensive than the modules usually fit on them. This could be because freighters are used to carry items and do almost no fighting. The ones appearing on the killmails could be shot down by a fleet of players seeking the cargo in the freighter. This means these freighters do little combat, and so there would not be a good reason to over-spend on modules that only marginally increase its power.

However, this graph is a logarithmic graph, so a slight deviation from the line means a multiplication or division by a not insignificant number. So any attempts to predict the prices will be off by several times.

Q3: Is the popularity of modules different when fighting player and non-player enemies?¶

In [53]:
plt.figure(figsize=(200,100))
sns.barplot(x = inv["typeName"][pnp.index.values], y=pnp["P"])
plt.title("Usage rates of modules in PvP scenarios")
plt.xlabel("Modules")
plt.ylabel("Usage rate")
Out[53]:
Text(0, 0.5, 'Usage rate')
In [54]:
sns.kdeplot(data=pnp["P"])
plt.title("Density of modules over the PvP usage rate")
plt.xlabel("PvP usage rate")
Out[54]:
Text(0.5, 0, 'PvP usage rate')

From the graphs, we notice that the PvP usage rate of modules or ships is approximately normally distributed, but with a slight left skew and a slightly flatter top end. This means that items are not as unlikely to have PvP usage rates that are slightly above or below 50%.

This means that the popularity of items is, on average, different against player or non-player enemies. This means that PvP or PvE fights are different enough that there are many items that would be preferred for one situation or the other.

So yes, the popularity of modules or ships does tend to be at least slightly different for PvP or PvE situations.

Additionally, from the top end, there are things that are only used in PvP situations.

In [55]:
plt.figure(figsize = (20,10))
plot = sns.barplot(x = inv["typeName"][pnp[pnp["P"] == 1].index.values], y=pnp[pnp["P"] == 1]["P"])
plot.set_xticklabels(plot.get_xticklabels(), rotation=30, ha="right")
plt.title("Modules or ships exclusively used in PvP")
plt.xlabel("Modules")
plt.ylabel("PvP Usage Rate")
plt.show()

Judging from the module names, these are modules that are fit on structures and capital ships, along with such structures and capital ships. This is likely because they are massive and impractical to use on raiding the generally more secluded bases of pirates and other non-player enemies. Additionally, structures are rooted, so it is impossible to use them to attack things that are not players, as they do not move out from their bases.

Q4: Given a certain module which modules are most commonly fit alongisde it?¶

In [56]:
normalized = (grouppair2 / grouppair2.sum()).T
normalized.columns = marketgroups["marketGroupName"][pd.to_numeric(normalized.columns.values).tolist()]
normalized.index = marketgroups["marketGroupName"][pd.to_numeric(normalized.index.values).tolist()]
normalized.index.name = "row"
normalized.columns.name='column'
fig = px.imshow(np.log(np.log(normalized+1)+1), text_auto = True, width=600, height=500)
fig.update_layout(title_text = "Which module groups are commonly paired together?", yaxis_title = "", xaxis_title = "").update_yaxes(automargin=False).update_xaxes(automargin=False)
fig.show()
#plt.show()

The trend seems to be that modules are paired with their rigs, for example the scanning rigs are paired with scanner modules, harvesting equipment is paired with resource processing rigs, electronic warfare is paired with their rigs, etc. This makes sense as rigs have bonuses to that specific item. In addition, items of similar types seem to also be paired with each other, like structure engineering rigs, electronic warfare and energy neutralizers, scanning equipment with other scanning equipment, etc. The brighter points on the heatmap are the pairs of module groups that occur the most number of times relative to other pairs.

Recommendations or Further Works

State any recommendations, improvements or further works.
  • With more market data, in the future it may be benefitical to analyze the market more with how it affects the usage of modules.
  • With more time I could better sort out the item groups to filter the more useful groups.
  • I could also make a dedicated application to access the usage rate of modules instead of just plotly and zooming. This would be helpful in the game itself.
